    #   HOW TO BUILD THE SEMI-STATIC MODULE:
    #   ------------------------------------
    #
    #   A) install the Python development package
    #
    #   B) build or install static libraries of current versions of
    #      libaudiofile, libesd, SDL and smpeg
    #      (distributions like Debian have packages for all of these)
    #
    #   C) build your own stripped down SDL 1.2.7 library from source
    #     1) configure SDL with `--disable-shared --disable-arts --disable-video
    #          --disable-events --disable-cdrom --disable-joystick'
    #     2) build SDL
    #     3) copy the resulting library src/.libs/libSDL.a to
    #        /usr/local/lib/libSDL-1.2.7-disable_video.a
    #
    #   D) build the semi-static pysolsoundserver module
    #     1) run `./configure'
    #     2) type `make static'
    #     3) type `make strip' (optional)
    #     4) type `make install'
    #
